IMPROVEMENT IN PAPER DISHES.

Specification forming part of Letters Patent No- 20S,096, dated September 17, 187B application filed May 22, 1878.

To allwhom it may concern:

Be it known that I, HENRY A. HoUsE, of Bridgeport,Fairfield county, Connecticut, have invented Improvements in Paper Dishes for Butter, 820;, of which the following is a specification:

My invention relates to that class of dishes made of paper intended for groceries, &c., and constituting the receptacles of the articles when sold; and my invention consists in constructing the paperdish, having corrugated sides, with an edge rib following the edges of the corrugations, as fully described hereinafter, to impart strength and rigidity.

In the drawings, which form part of this specification, Figure l is an outside view of my improved dish, Fig. 2, a transverse section; Fig. 3, a plan view, and Fig. 4 a view showing the ordinary form of dish.

Corrugated paper butter-dishes, 850., heretofore made have been formed by turning up the sides and ends of the sheet of paper, either in dies or otherwise, so that the edge of the said sheet constitutes the upper edge of the dish.

In order to impart, strength and rigidity to the corrugations, I bend the upper edge over so as to form a flange, a, of the curved shape shown in the section, Fig. 2. This flange not only prevents the rupture of the edge above referred to, but it braces the dish laterally and longitudinally, and, following the upper edge of said corrugations, tends to preserve their form under. the pressure or other effects of material within the dish, and to prevent them from being broken from pressure from the outside.

As the curved flange cannot be formed by ordinary dies, I employ peculiar apparatus, which need not be here described, as it constitutes the subject of a separate application for Letters Patent.

I do not claim, broadly, a paper butter-dish with a flange at the edge, as this is the invention of Chalmers Ingersoll, but

I claim- A butter-dish made of paper and provided with corrugated sides, having a continuous flange following the edge of the corrugations, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
